WINDOW-LOCK.

SPECIFICATION formingpart of Letters Patent No. 762,616, dated. June 14, 1904.

Application filed January 25, 1904;.

T (ti/Z whom it may concern.-

Be it known that I, WILLIAM E. CoNNER, a citizen of the United States of America, residing at Braddock, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Window- Locks,of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wind ow-locks, and has for its object to provide a window-lock which when once fastened will be securely held and all attempts to open the same from the ex- 5 terior prevented.

Another object of my invention is to provide means whereby the sashes of a window may be easily raised or lowered and locked in any desired position.

Briefly described, my improved window-. lock consists of providing each sash of the window with racks which are adapted to mesh with a plurality of pinions mounted in the frame of the window, means being provided 5 in connection with these pinions whereby the sashes of the window will be held in their normal position, and means are provided adjacent to these pinions for locking the same and preventing them from rotating.

WVith the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this application, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a front view of a portion of a window, showing the meeting-rail of the'two sashes. Fig. 2 is a horizontal sectional view of one side of the frame and a portion of the sashes. Fig. 3 is a side elevation of the pin- 45 ion-wheels and a portion of one'of the sashes.

Fig. 4 is a vertical sectional view of the frame,

showing the pinions and locking mechanism in side elevation. Fig. 5 is a detail perspective view of the locking mechanism. Fig.

Serial No. 190,531. (No model.)

I 6 is a detail view of the upper end of one of 5 .the locking-jaws.

In carrying out my inventionl have illustrated a portion of the frame of the window, as indicated by the reference-numeral 1, and in this frame are the sashes 2 and 3. Upon the sides-of these sashes I secure a vertical rack 4, which is adapted. to mesh with pinions 5, mounted in the side walls 6 of the frame 1. These pinions are otherwise supported by a vertical partition 7, which cen- 6o trally of its length carries a bracket 8, having outwardly-extending stub-shafts 9, and upon these shafts are mounted pinions 10, which are adapted to mesh with the pinions 5. These pinions 1O areloosely mounted, and connected they are released by the locking mechanism.

In the side walls of the casing or frame I provide projecting pins or lugs 15, between which are mounted the T-shaped locking-jaws 16, these jaws having teeth 17 formed on their lower ends, which are adapted to engage the teeth of-the pinions 10 when they are lowered.

In the upper end of these jaws I provide an aperture 18, through which passes a rod 19,which is mounted in the side walls 6 of the frame,

as illustrated in Fig. 4 of the drawings. This rod carries elliptical-shaped lugs 20, which are adapted to engage in the apertures 18 of the jaw 16, and when the rod 19 is rotated by means of the button 21, carried on the end of the rod, the jaws will be raised from disengagement with the pinions 10, this movement being partially illustrated in Fig. 6 of the drawings.

Each of the springs 12, which is under tension, is adapted to hold the sashes in their closed position, and if the sash 2 was lowered and not locked in this position the spring carried on the hub of the'pinion operated would have atendency to return it to its closed position. The same is true of the lower sash if it was raised withoutbeinglocked. It will thus be seen by this construction that all weights generally used are dispensed with and that the sashes of the window may be easily and quickly raised or lowered to any position, and by retating the button carried by the rod of the locking mechanism the window-sashes may be locked in any desired position, the jaw 16 normally engaging the pinions by their own weight and prevented from becoming disengaged by the pins 15, carried by the side walls of the window-frame.

It will be obvious that various slight changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the window-frame and the upper and lower sash thereof carry ing racks, pinions in mesh with each other and engaging said racks, vertically-movable toothed jaws for engagement with one of the pinions, said jaws being apertured, and a rod carrying lugs received in the jaw-apertures to actuate said jaws.

2. In combination with the window-frame and the upper and lower sash thereof, means for engagement with the sash for automatically closing the same, comprising in part a toothed member, vertically-movable jaws having their lower ends toothed for engagement with said toothed member and their upper ends apertured, and a rod carrying lugs received in said apertures to operate said jaws.

In testimony whereofI affix my signature in the presence of two witnesses.

WILLIAM E. (JONNER.
